Application .filed March 22, 1916. Serial No. 85,827.

To all whom if may concern:

Be it known that I, VILLIAM M. ROHN, a residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Razor Honing and Stropping. Devices, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in i'azor stropping and honing devices, it being more especially adapted for use in connection with safety razor blades, one object of the invention being the provision of a device of this character which is provided with a blade carrying and coperative shifting means for placing the blade in proper cooperation with the honing and stropping member, as the same is reciprocated.

A further object of this invention is the provision of a stropping'andhoning device which is simple, durable and inexpensive in construction and thoroughly eliicient and practical in use.

With the foregoing and 'other objects in view, and which will appear as the description proceeds, this invention resides in the novel arrangement and combination of parts as herein set forth, it being possible, however,'to change the details of construction,-

which are only limited by what is claimed.

In the accompanying drawings;-Figure 1 is a top plan view, the strop being broken away. Fig. 2 is a side elevation thereof. Fig. 3 is a section taken on line 3 3 of Fig. 2. Fig. f1 is a top plan view of the stropping and honing member, a portion being broken away to show the resilient connection between the ends. Fig. 5 is an enlarged detail sectional view of the honing portion of the strop. Fig. 6 is a plan `view of the blade carrier blank.

Referring to the drawings the numeral 10 designates the two side plates, which are connected together by means of the spacing plates 11 and thus constitute 'a supporting structure or frame for the device.

The side plates are each provided with the two parallel slots 12 and 13, while mounted for sliding movement adjacentthe outer faceof such plates are the depending flat ends 13 of the carriage 14 having the connecting member 15 to which is detachably connected the manipulating handle 16. Journaled between thedlat ends and extending between the plates 10 and through the Aof the lower shaft and -tion of the springs, such surface will rota-te lower slots 13 is a shaft 14 which is provided with the corrugated surface 17 and has fast lthereto the gear or pinion 18. Also mounted in the carriage above the last mentioned shaft is the blade carrier or clamp 19 which with its journaling pintles 20 is made from a single sheet of metal, as illustrated in Fig. G, such pintles being extended through the upper slots 12. and one thereof having seciired rigidly thereto the pinion 21 which is in mesh at all times with the pinion 19.

The razor blade 2l is adapted to be removably fitted in the clamp 19 so that the edge thereof will always be projected in the opposite direction -to the movement of the carriage. 1n order to insure this, a metal strip 22 is provided with openings 2S at the terminals thereof for receiving the supporting springs 2% which in turn are connected to the upper edges of the retaining plates 11. In this manner, the strip is supported re- `silieutly so that the relatively soft friction surface 0r strap 25 connected to the upper surface thereof and preferably made of leather will engage the corrugated portion due to the coperathe shaft at the initial movement of the carriage so as to dispose the blade away from the direction of travel of the carriage and upon the honing and stropping member 26,' the continued movement of the carriage and the coiiperation between the corrugated shaft and the leather strap maintaining a steady pressure upon the blade relatively to the-stropping and honing member. This sti'oppiiig and honing member is preferablyT made of a striprof flexible material, leather or the like, and is adapted to be disposed around the rollers 28 mounted upon the rods 29 and between the corrugated shaft and the blade carrying member of the carriage, the ends of the same boing each provided with the nietal connections or pieces 3() whiclrin turn are provided with the eyes 31 for the reception of the spring 32 which thus holds the flexible member at the proper tautness at all times. l

The button or handle 33 is connected so that the flexible member.constitutinggthe strop or hone maybe moved longitudinally to present the stropping surface 34 or the honing surface 35 to receive the blade dur- 'ing the reciprocation of the carriage.

l lia n woohoo 'the surface of the strop and filling such ya frame, a carriage mounted therein for reciprocation, a shaft journaledl in the carriage, a blade carrying clamp also journaled in the carriage, cooperative transmission means between the clamp and the shaft, a

honing and stropping member carried by the frame and interposed between the shaft and the clamp, and means disposed in the path of the shaft for cooperating therewith to rotate thesame at the initial movement of the carriage and for maintaining the clamp with .its free edge toward and upon the stropping and honing member.

2. In a device 'of the character described,

a frame having two side plates provided each with two longitudinal parallel slots therethrough, a carriage having two side members fitting astride of said plates for reciprocatiori, a shaft journaled in said side members in the carriage and projected transversely in the frame through the lower slots thereof, a blade carrier iournaled in said carriage and spaced from the shaft, transmission means between the shaft and the blade carrier, whereby t'he blade carrier is rotated through the sha ft, resiliently supported friction means mounted within the frame and in contact with the shaft, whereby as the carriage is reciprocated. said shaft is rotated, and a razor stropping and honing member mounted in the frame, between the shaft and blade carrier.

3. ln a device of the character described, a frame having' two side plates provided each with two longitudinal parallel. slots therethrough, a carriage having two side members fitting' astridc of said plates for reciprocation, a shaft journaled in said side members in the carriage and projected. trans- -versely in the frame through the lower slots thereof, a. blade. carrier journaled-in said Ycarriage' and spaced from the shaft, trans:

mission means between the shaft and the blade carrier, whereby the blade carrier is rotated thrfnigh the shaft, resiliently supported friction means mounted within the frame and in contact with the shaft, whereby as the carriage is reciprocated, said shaft is rotated, a flexible strop passed. between the shaft and blade carrier and mounted within the frame, and a spring connecting; the terminals lof said strop to impart a resilient tautness to the strop.

Il. In a device of the character described, a frame composed of two side plates and two transverse retaining plates, a carriage mounted for movement upon the side plates, a shaft carried by thev carriage, a blade carrier also carried by the carriage and operlably connected to the shaft, a resiliently supported member connected to the retaining plates and disposed longitudinally within the frame and for contact with the shaft whereby at the initial movement of the carriage in 'either direction, the shaft is rotated .to project thenblade carrier in an opposite direction tothe movement ofthe carriage.

5. In a device of the character described, a frame composed of two side plates and two transverse retaining plates, a carriage mounted for movement upon the side plates, a shaft carried by the carriage, a blade carrier also carried by the carriage and operably connected to the shaft, a resiliently supported member connected to the retaining plates and disposed longitudinally within the frame and for contact with the shaft whereby at the initial movement of the carriage in either direction, the shaft is'rotated to project the blade carrier in an opposite direction to the movement of the carriage, and a flexible honing and stropping` member disposed around the retaining,` plates and between the shaft and bla-de carrier for receiving the cutting edge of the blade during the reciprocation of the carriage.

6. In a device of the character described,

a frame, a carriage mounted thereon forreciprocation, an oscillatory blade carrier mounted in the carriage, land cooperative means for shifting the blade carrier respectively'mounted in the carriage and supported by the frame, the portion thereof supported by the frame being held resiliently so as to exert aresilient tension upon theaarting longitudinal movement to the mem. 115- l ber to dispose the stropping orf honing portions thereof 1n active position, and a blade manipulating carriage mounted for sliding movement. in the frame and in co-active re` lation with 'the honing;- and stropping mem- 120 ber.
